(Indignity is put over them wherever they may be, except when under a covenant (of protection) from Allah, and from men;) ﴿3:112﴾, in reference to pledges and peace treaties.

Allah's statement

﴿وَلاَ تَفَرَّقُواْ﴾

(and be not divided among yourselves), orders sticking to the community of the believers and forbids division. There are several Hadiths that require adhering to the Jama`ah (congregation of believers) and prohibit division. Muslim recorded that Abu Hurayrah said that the Messenger of Allah said,

(It pleases Allah for you to acquire three qualities and displeases Him that you acquire three characteristics. It pleases Him that you worship Him Alone and not associate anything or anyone with Him in worship, that you hold on to the Rope of Allah altogether and do not divide, and that you advise whoever Allah appoints as your Leader. The three that displease Him are that you say, `It was said,' and, `So-and-so said,' asking many unnecessary questions and wasting money.)

(and remember Allah's favor on you, for you were enemies one to another but He joined your hearts together, so that, by His grace, you became brethren) ﴿3:103﴾.

This was revealed about the Aws and Khazraj. During the time of Jahiliyyah, the Aws and Khazraj were at war and had great hatred, enmity and ill feelings towards each other, causing long conflicts and battles to occur between them. When Allah brought Islam, those among them who embraced it became brothers who loved each other by Allah's grace, having good ties for Allah's sake and helping each other in righteousness and piety. Allah said,

(He it is Who has supported you with His Help and with the believers. And He has united their hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allah has united them)﴿8:62,63﴾, until the end of the Ayah. Before Islam, their disbelief had them standing at the edge of a pit of the Fire, but Allah saved them from it and delivered them to faith. The Messenger of Allah reminded the Ansar ﴿from both Aws and Khazraj﴾ of this bounty when he was dividing the war booty of Hunayn. During that time, some Ansar did not like the way the booty was divided, since they did not get what the others did, although that was what Allah directed His Prophet to do. The Messenger of Allah gave them a speech, in which he said,

(O Ansar! Did I not find you misguided and Allah directed you to guidance because of me Were you not divided beforehand and Allah united you around me Were you not poor and Allah enriched you because of me)

Whenever the Prophet asked them a question, they would answer, "Indeed, Allah and His Messenger have granted us bounty.''

(104.Let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma`ruf (all that Islam orders) and forbidding Al-Munkar (all that Islam has forbidden). And it is they who are the successful.) (105. And be not as those who divided and differed among themselves after the clear proofs had come to them. It is they for whom there is an awful torment.) (106. On the Day (i.e. the Day of Resurrection) when some faces will become white and some faces will become black; as for those whose faces will become black (to them will be said): "Did you reject faith after accepting it Then taste the torment (in Hell) for rejecting faith.'') (107. And for those whose faces will become white, they will be in Allah's mercy (Paradise), therein they shall dwell forever.) (108. These are the Ayat of Allah. We recite them to you in truth, and Allah wills no injustice to the `Alamin.) (109. And to Allah belongs all that is in the heavens and all that is in the earth. And all matters go back (for decision) to Allah.)
